hi NXP

i am using libfslvpuwrap-1.0.46

i would like to know whether GOP option is working ?

i am using gstreamer-0.10 (which we can not change)

requirement is get SPS/PPS at every regular interval (proper usage of GOP)

but GOP option is not working ?

did we have any patch for this ?

regards

nagendra

what command do you use? you can use "vpuenc gopsize=", and one can try to use unit test, but the latest gstreamer version is 1.0, we haven't updated 0.1 version anymore

hi nxp

thanks for reply

let me put my questing in more clear way

i am using gstreamer-0.10 (which we can not change now due to some reasons)

and i am streaming encoded video through mpedtsmux and working fine

i used vpuenc widh sequence-header=3 option , which gives SPS/PPS with all encoded frames..and working fine

now the requirement is to get SPS/PPS infor at regular intervals (i think IDR frames at regular intervals) we no need SPS/PPS info at every frame !

i tried usign GOP opting to vpuenc but not working. (vlc unable to decode at the other end of stream)

so, i would like to know any patch which can be applied to vpu library to achieve this?

thanks
